The 800 Series is designed for serious performance and excursion. It features a DD cast basket supporting a triple stack, 75mm thick magnet motor, long throw suspension, and a high strength cone coupled to a massive EROM surround, making them best suited for duty in vented or multi-order enclosures.
The 4.0” diameter USA made aluminum flat wire coil is powered by a huge 25mm top plate. It has the headroom needed for extended bass sessions, and is cooled by both voice coil and motor vents.
